描述
数字视频评估模块让开发者可以建立对达芬奇处理器的即时评估，并开始构建数字视频应用，例如可视电话，车载信息娱乐系统，数码相机，媒体， IP机顶盒，视频安全监控系统和还没有被发明的数字视频产品。 NOTE: You must register your DVEVM in order to access software updates and receive update notices. Register NowView the DVEVM in 3DThe Digital Video Evaluation Module (DVEVM) allows developers to write production-ready application code for the ARM and provides access to the DSP core using DaVinci APIs to begin immediate application development for the TMS320DM6443 and TMS320DM6446 digital media processors.The DVEVM includes TI’s eXpressDSP DM664x Linux DVSDK. The eXpressDSP Digital Video Software Development Kit allows DaVinci system integrators to incorporate discrete software modules and combine them into a single executable output for systems, avoiding months of tedious manual integration. By making it easy to create custom bundles of codecs for specific applications, the configuration kit makes it simple to reuse code.DVSDK software features:
- TI video, imaging, speech and audio evaluation codecs
- Custom codecs that comply with TI’s eXpressDSP™ Digital Media (xDM) algorithm standard
- Demonstration versions of popular video codecs to enable developers to benchmark and evaluate performance parameters
- Multimedia Application Programming Interfaces (APIs)
- TI’s Codec Engine framework (Audio/Video)
- DSP/BIOS™ real-time kernel
- TI DSP/BIOS Link interprocessor communication technology (available in the Linux-based DVSDK)
- MontaVista Pro Linux demonstration software
The TMDSADP1420 adapter is used for connecting TI and 3rd party XDS510 and XDS560- class emulators with a 14 pin native connector to the TMDSEVM6446 or customer boards with a compact (CTI) 20-pin header. The adapter improves signal integrity, translates voltages, and can optionally provide adaptive clocking.The hardware for the DM6446 Digital Video Evaluation Module (DSP13078U) and the DM6446 Digital Video Evaluation Module with European Power Cords (DSP13081U) differ slightly per the following:DM6446 Digital Video Evaluation Module - (DSP13078U)
- TMS320DM446 DaVinci™ processor-based development board
- NTSC video camera
- NTSC LCD screen, speakers and microphone
- IR remote
- Hard disk drive (2.5-inch 40G)
DM6446 Digital Video Evaluation Module with European Power Cords - (DSP13081U)
- TMS320DM446 DaVinci™ processor-based development board
- PAL video camera
- PAL LCD screen, speakers and microphone
- IR remote
- Hard disk drive (2.5-inch 40G)
特性
The DVEVM is a complete out of box experience. The developer can turn on the board and hook up the included LCD screen. The board will boot MontaVista Linux and run a GUI that can be controlled by the included IR remote. The GUI includes access to three demos and the ability to run five different codec combinations.| The demos are: | | Video and Audio decode | | Video and Audio encode (uses included camera) | | Simultaneous Video decode/encode |
| The five codec combos are: | | R1.1.1 | H.264 Video Encode, H.264 Video Decode | | R1.2.1 | H.264 (Baseline Profile) Video Encode, G.711 Speech Encode | | R1.2.2 | MPEG-4 (Simple Profile) Video Encode, G.711 Speech Encode | | R1.3.2 | MPEG2 Video Decode, MPEG1 Audio Decode | | R1.3.1 | H.264 (Baseline Profile) Video Decode, AAC Audio Decode | | R1.3.3 | MPEG-4 (Simple Profile) Video Decode, G.711 Speech Decode |
| These available demo codecs are on the DVEVM. | | AAC+ | MPEG4 | | G7.11 | MPEG2 | | H.264 | |
| These codecs are available for production licensing from TI and will be on future development platforms. | | WMV9 | WMA8 | | VC1 | MP3 | | JPEG | G.728 | | AAC | G.723.1 | | WMA9 | G.729ab |
